Index No: NBM056330; Collected By: ; Sample Type: hand sample; Notes: Composite rock chip sample across 2 m of a 1-3 m-wide zone of vein and vein-cemented breccia . White to clear and light gray, fine grained, crustiform, banded, comb quartz, locally drusy, and with local boxwork texture after bladed calcite. Vein strikes N80�E, dips 65�S here. Adjacent wallrock is silicified and adularized, flow-banded, porphyritic rhyolite lava/dome. Strong iron oxide coatings; wallrock was probably pyritic before weathering, oxidation. Sample was collected on Stonewall Mountain east of Stonewall Spring. -Weiss 5/18/95.
